About Roof Scuppers
A scupper is a drainage opening located in the edge of a roof or parapet wall that allows water to drain off the roof surface. In commercial roofing, scuppers are often used in conjunction with gutters and downspouts to effectively manage stormwater runoff and prevent ponding water. They are typically lined with metal to protect the wall structure and ensure water is directed away from the building exterior.
Frequently Asked Questions
Why are scuppers important for flat roofs?
They provide a critical pathway for water to exit the roof, preventing excessive weight and potential structural damage from ponding water.
Do scuppers need to be cleaned?
Yes, scuppers must be regularly inspected and cleared of debris, leaves, and ice to ensure proper water flow.
What happens if a scupper is blocked?
A blocked scupper can lead to severe water accumulation on the roof, increasing the risk of leaks and structural collapse.
